Social network analysis: the use of graph distances to compare artificial and criminal networks
2021
Aim: Italian criminal groups become more and more dangerous spreading their activities into new sectors. A criminal group is made up of networks of hundreds of family gangs which extended their influence across the world, raking in billions from drug trafficking, extortion and money laundering. We focus in particular on the analysis of the social structure of two Sicilian crime families and we used a Social Network Analysis approach to study the social phenomena. Starting from a real criminal network extracted from meetings emerging from the police physical surveillance during 2000s, we here aim to create artificial models that present similar properties. Methods: We use specific tools of s…
Tourist destination network analysis: The ego network role
2017
This paper aims to analyse the different roles that enterprises have within a tourist destination by identifying the presence and possible role of leaders within the system. The Social Network Analysis (SNA) is a tool that offers a greater degree of understanding of the operation of the destination. The map of commercial relations between the leading players of tourist supply can provide greater insight into the main relations existing between enterprises and the principles that ensure and regulate operation. In keeping with this objective and building on the results of a previous paper (Iannolino and Ruggieri, 2012), the authors have focused their attention on the role of some enterprises …
Sustainable development goals research in higher education institutions: An interdisciplinarity assessment through an entropy-based indicator
2022
Since 2015, the United Nations has urged higher education institutions (HEIs) to adopt an interdisciplinary approach towards the Sustainable Development Goals (SDGs). In other words, universities are encouraged to transcend any single disciplinary perspective in exploring sustainable development issues. This study examines the importance of driving the scientific production of HEIs towards the SDGs as a concrete institutional contribution to sustainable development. While bibliometric tools for the SDGs are currently emerging, the existing models have not focused on interdisciplinarity or on their usefulness as decision-management tools to drive SDG-related research at a micro-scale (i.e. t…
Redes, complejidad y Arqueología: otra forma de ver el pasado
2018
La ciencia moderna se ha benefi ciado de los intentos del positivismo y neopositivismo por explicar el mundo sensible, que han generando grandes avances en el mundo de la ciencia, pero que han tenido problemas a la hora de plantear una “Teoría del Todo”. Hay que destacar el hecho de que toda explicación de la realidad es siempre un modelo simplifi cado, que se basa en alguna teoría. Durante los años 90, con el fi n de avanzar en la comprensión de la realidad empírica, comenzaron su andadura lo que se conoce co mo Ciencias de la Complejidad. A través de ellas se pretende explicar una serie de fenómenos comúnes a todos los sistemas formados por elementos interrelacionados, que como un conjunt…
Tourism destination and the role of trust
2012
Tourism destinations increasingly pose new challenges to the organizational and management aspects of tourism. The non-cooperative behavior of some companies, the difficulties of sharing a system of values, the absence or inadequacy of destination managers keep some destinations off the map of growth that is sought for by the stakeholders and shareholders of a given resort. This difficulty seems to lie in the scarce knowledge of the system of relations existing between firms and their degree of cooperation. The application of Social Network Analysis (SNA) and some indicators for network analysis provides a clearer and more analytical map of the links between tourism businesses located withi…
